Fix Recommendation

The pam_cracklib module's "lcredit=" parameter controls requirements for usage of lower-case letters in a password. When set to a negative number, any password will be required to contain that many lower-case characters.

Edit /etc/pam.d/system-auth and /etc/pam.d/password-auth adding "lcredit=-1" after pam_cracklib.so to require use of a lower-case character in passwords.

Check Contents

To check how many lower-case characters are required in a password, run the following command:

$ grep pam_cracklib /etc/pam.d/system-auth /etc/pam.d/password-auth

Note: The "lcredit" parameter (as a negative number) will indicate how many lower-case characters are required. The DoD requires at least one lower-case character in a password. This would appear as "lcredit=-1".

If “lcredit” is not found or not set to the required value, this is a finding.
